Since R 3.5 (I don't remember this happening in R 3.4.x) signals sent from interrupting
|
|
|
|
|
Athena JDBC calls crash the R #' interpreter. You need to set the \code{-Xrs} option to avoid
|
|
|
|
|
signals being passed on to the JVM owner. That has to be done \emph{before} \code{rJava} is
|
|
|
|
|
loaded so you either need to remember to put it at the top of all scripts \emph{or} stick this
|
|
|
|
|
in your local #' \code{~/.Rprofile} and/or sitewide \code{Rprofile}:\preformatted{if (!grepl("-Xrs", getOption("java.parameters", ""))) {
|
|
|
|
|
options(
|
|
|
|
|
"java.parameters" = c(getOption("java.parameters", default = NULL), "-Xrs")
|
|
|
|
|
)
|
|
|
|
|
}
